Stacking double-hanging processing method and device

Abstract

The invention relates to the technical field of stacking, and provides a stacking double-hanging processing method and device, which are used for solving the problem of service interruption generated by a stacking double-hanging scene, the method is applied to first equipment of which the equipment type is main equipment in a VSU system, and the method comprises the following steps: according to equipment information of the VSU system, determining that second equipment of which the equipment type is slave equipment exists in the VSU system, sending a first heartbeat message to the second equipment, and obtaining a network connection state between the first equipment and upper-layer equipment; and after it is determined that the network connection state is abnormal and the first heartbeat response message sent by the second equipment is not received within the preset first time period, performing a reset operation. When the first equipment determines that the first equipment is the master equipment and the second equipment operating as the slave equipment also exists in the VSU system, after determining that the network connection state is abnormal and the first heartbeat response message is not received on time, the first equipment performs reset operation, processes the stacked double-hanging scene and quickly recovers the service of the VSU system.

Description

technical field [0001] The present application relates to the field of stacking technology, and provides a stacking double-hanging processing method and device. Background technique [0002] refer to Figure 1a The schematic diagram of the traditional network architecture shown shows that dual-core devices are used in the core layer or aggregation layer. Although this improves the performance and reliability of the network, it also increases the complexity of the network, and a large number of backup links It also reduces resource utilization. In order to solve the above problems, a virtual switching unit (Virtual Switching Unit, VSU), a network system virtualization technology, was introduced when designing the network architecture, which virtualized multiple physical switches into one virtual switch, and multiple physical switches constituted a network system. A VSU system. refer to Figure 1b It can be seen from the schematic diagram of the network architecture using t...
